Comparison

The best MCP servers for SEO, and what each one is actually for

Most “best MCP server” lists rank tools that do completely different jobs. These six do not compete — they cover rank tracking, first-party search data, raw SERP data, link indexes and crawling. Pick by the question you want your assistant to answer.

We make one of these. Details below were read from each vendor’s own public documentation in September 2026; check current pricing with the vendor before you commit.

Pick by the job

The job	Use	Why
Watching your own Google positions over time	LemRank MCP	It is the only one here that stores a daily history of your keywords, so the assistant can answer what changed.
Reading your own Search Console data	A Search Console MCP	First-party clicks and impressions, free, at the cost of self-hosting and a service account.
Raw SERP and keyword data on demand	DataForSEO MCP	The widest catalogue, billed per call. Best when you want data, not a tool.
Backlink and competitor research	Ahrefs or Semrush MCP	Both need a paid API allowance on top of the subscription you already pay for.
Technical crawling	Screaming Frog MCP	Runs a real crawl locally. Nothing remote matches it for on-page detail.

The servers in detail

LemRank MCP

LemRank

What it exposes: Daily Google rank tracking: your tracked keywords, current and historical positions, SERP features, URL-level analysis, and adding keywords to tracking.
Cost: Included with any paid plan; free trial available.
Where it falls short: Best when the question is 'where do my keywords rank and what moved'. It has no site crawler and no third-party backlink index.

DataForSEO MCP

DataForSEO

What it exposes: Live SERP results, keyword data, on-page checks and backlink data across a large API catalogue.
Cost: Pay per API call on top of a DataForSEO balance.
Where it falls short: The widest raw data, but it is a data supplier: costs scale with every question the assistant asks, and nothing is tracked over time for you.

Vendor documentation

Semrush MCP

Semrush

What it exposes: Semrush analytics: domain and keyword research, competitor overlap, and other API endpoints your subscription covers.
Cost: Requires a Semrush subscription with API units.
Where it falls short: Strong for research and competitor analysis. API units are consumed per call and are separate from the seat price.

Vendor documentation

Ahrefs MCP

Ahrefs

What it exposes: Ahrefs index data: backlinks, referring domains, organic keywords and site metrics.
Cost: Requires an Ahrefs API plan, priced separately from the standard subscription.
Where it falls short: The reference choice for link data. The API plan is a significant extra cost for small teams.

Vendor documentation

Google Search Console MCP

Community open source

What it exposes: Your own Search Console data: clicks, impressions, CTR, average position, by query, page and country.
Cost: Free, but you self-host and manage a Google service account.
Where it falls short: Real first-party data, and free. The setup is developer work, and Search Console only shows queries you already appear for.

Screaming Frog MCP

Community open source

What it exposes: Drives a local Screaming Frog crawl and returns technical crawl findings to the assistant.
Cost: Needs a licensed Screaming Frog install on the machine running it.
Where it falls short: The right tool for technical audits. It runs locally, so it cannot answer questions when your laptop is closed.

Vendor documentation

If the question is “what moved?”

That one needs a tracker behind it. LemRank checks your keywords daily and hands the history to your assistant over MCP.
